It presents two analysis that demonstrate vertexing and tagging capabilities useful for furhter time-dependent CP violation measurments. The first analysis uses partially reconstructed $B^{0} \rightarrow D^{*+}l \nu $ decays combined with an additional high momentum lepton in the rest of the event. The latter one uses fully reconstructed hadronic decay final states $ B^{0} \rightarrow D^{(*)\mp }X^{\pm}$ 000001676 700__ $$aOn behalf of Belle II collaboratrion 000001676 8560_ $$freem.rasheed@desy.de 000001676 8564_ $$uhttps://docs.belle2.org/record/1676/files/BELLE2-CONF-PROC-2019-012.pdf
